As IoT technology grows, several different payment methods are available now. NFC (Near Field Communication) as a short-range communication technology has been applied in many fields, such as contactless payment and electronic tickets. ATM (Auto Teller Machine) also benefits from NFC technology as one way of cardless cash withdrawal. However, there are many security problems, and convenience problems exist. In security, certain kinds of attacks, such as man-in-the-middle, replay, and brute-force attacks, must be considered. These attacks may influence user privacy. Furthermore, considering user experience, existing methods may not make users feel enough convenience when using. To enhance security and user experience, we proposed a secure NFC cardless cash withdrawal system using time stamps and nonce to reduce the risk of attack and design more effortless operations for users to enhance user experience. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

This paper reports on the influence of various processing parameters and different SiCp proportions on the outcome of mechanical, tribological, microstructural, and microcompositional investigations of Al-Cu based composites used as potential brake friction materials for eco-friendly vehicle parts. The composites were obtained by powder metallurgy, and then the sintered composite was treated at 515 ± 5 °C/6 h, quenched in water, and artificially aged at different temperatures and times. The microstructural and microcompositional investigations of the composites were made using an environmental scanning electron microscopy (ESEM), energy-dispersive X-ray spectroscopy (EDS). After analyzing the microstructures in correlation with the results of the hardness tests, the optimal proportion of SiCp and optimal heat treatment parameters were determined. The composite samples with the best properties were chosen for tribological investigation. The friction and wear tests of samples were made under dry sliding conditions using a "pin on disc" machine, at a contact pressure of 0.35 to 1.15 MPa, 2 to 4.5 m/s relative speed, and the prediction of tribological behavior was made using a linear factorial design approach. © 2025 by the authors.

Entity-relationship and object-oriented data modeling - An experimental comparison of design quality

引用

DATA & KNOWLEDGE engineering 1997年第3期21卷 297-315页

We compare EER and OO data models from the point of view of design quality. Quality is measured in terms of (a) correctness of the conceptual schemas being designed, (b) time to complete the design task, and (c) designers' preferences of the models. Result of an experimental comparison of the two models reveal that the EER model surpasses the OO model for designing unary and ternary relationships, it takes less time to design EER schemas, and the EER model is preferred by designers. We conclude that even if the objective is to implement an OO database schema, the recommended procedure is to: (1) create an EER conceptual scheme, (2) map it to an OO schema, and augment the target schema with behavioral constructs that are unique to the 00 approach.

Determination of an implementation order for IS projects

引用

INFORMATION & management 1996年第2期31卷 67-74页

作者： Shoval, P Giladi, R Information Systems Program Department of Industrial Engineering and Management Faculty of Engineering Sciences Ben-Gurion University of the Negev Beer-Sheva 84105 Israel

The process of information systems (IS) planning in an organization occurs when there is a set of IS projects that require implementation, generally within certain time frames and budgetary constraints. We propose a method for determining an optimal order of project implementation. The proposed method utilizes the cost-benefit graph, which considers the expected cost and benefit of each of the projects comprising the set, as well as the weight (importance) of the cost and benefit factors to the decision-makers. The method allows us to analyze the sensitivity of a preferred implementation order to changes in cost and benefits, and the importance of these factors.

The design and implementation of a corporate householding knowledge processor to improve data quality

引用

JOURNAL OF management INFORMATION systems 2003年第3期20卷 41-69页

作者： Madnick, S Wang, R Xian, X John Norris Maguire Professor of Information Technology at the Sloan School of Management MIT Professor of Engineering Systems School of Engineering MIT Co-Director for MIT Total Data Quality Management Program Director MIT Information Quality Program Oracle Corporation

Advances in corporate householding are needed to address certain categories of data quality problems caused by data misinterpretation. In this paper, we first summarize some of these data quality problems and our more recent results from studying corporate householding applications and knowledge exploration. Then we outline a technical approach to a corporate householding knowledge processor (CHKP) to solve a particularly important type of corporate householding problem-entity aggregation. We illustrate the operation of the CHKP by using a motivational example in account consolidation. Our CHKP design and implementation uses and expands on the COntext INterchange (COIN) technology to manage and process corporate householding knowledge.

This work is unique and contributes new knowledge to the field whereas it involves introducing a new method based on coupling two or three stochastic models, analyzing new data represented by drought and flooding risk relationship, and addressing a previously unexplored research question: Can we make a decision regarding future evapotranspiration-flooding risk relationship? In this paper, the Bat algorithm (BAT) with the Newton Method (NM), Bird Swarm Algorithm (BSA), Genetic Algorithm (GA), and Chicken Swarm Optimization Algorithm (CSO) are used as a hybrid model in arid and semi-arid zones in Saudi Arabia as well as for modeling rainfall, temperature, and solar radiation implications on evapotranspiration variability. Coupling between aridity and evapotranspiration over a long time can create flooding risks. This holistic modeling aims to reduce flooding risks and ensure the desired decision. Several models were employed to simulate some basins’ Potential and Actual evapotranspiration as case studies. The meteorological inputs of the hybrid models were calibrated and validated with metric evaluation for input and output of evapotranspiration, respectively. The results suggest that the application of a hybrid model can improve the accuracy of evapotranspiration simulations in terms of statistical parameters, whereas BAT–GA–NM reduced MAPE from 38.88 to 4.16% for Mekkah and from 14.94 to 2.04% for Medina and NSCE from − 0.17 to 0.97 for Mekkah and from 0.82 to 0.99%. Those parameters will provide a better understanding of evapotranspiration processes in watersheds and valuable information for early warnings of flooding risks. © The Author(s) 2025.

33rd Annual International Conference of the American Society for engineering management 2012, ASEM 2012 - Agile management: Embracing Change and Uncertainty in engineering management

Interdependency among critical infrastructure (CI) is an increasing phenomenon. The 21st century has been defined by events that have changed individuals' perceptions of what CI is and its risks and vulnerabilities. One of the major critical infrastructures is the energy sector as described by public policy, and oil is an important component of this sector. This paper explores the relationships between oil and other infrastructures. We argue that the relationship between oil and other systems has changed the structure of the oil industry. How to manage this new structure is an emerging issue that requires attention from a systems approach. Whether oil is in its crude form or refined form, its value cannot be minimized due to its various applications. Oil and its derivatives are not an independent infrastructure;they are interconnected to other forms of energy and other infrastructures. These interconnections have increased risk and vulnerability from hostile nations, terrorists, criminals, and incompetent operators. We conclude that oil is critical to the well-being of humanity and yet is so fragile that it can be affected by cascading events from other critical infrastructure due coupling and pervasive computing technologies.

2015 122nd ASEE Annual Conference and Exposition

作者： Abel, Kate D. Bachelor of Engineering in Engineering Management Program School of Systems and Enterprises United States

About a decade ago, a movement was started at Stevens Institute of Technology to infuse the Capstone experience with systems engineering (SE) and engineering management (EM) knowledge. However the discipline specific Senior Design advisors did not have the time to teach, nor the in-depth awareness of, SE and EM topics to be able to provide their students with substantive learning on these subjects. A course soon emerged that would run along side the Senior Capstone Design course, to provide knowledge in these areas. The course exists in two formats. One format has been running for years as a traditional 3-credit, one semester course. The other format was implemented recently as a pilot to provide just-in-time learning over both semesters of senior design. Both formats have been running concurrently for three years. This article will address how the needs of the Senior Design Advisors from the various disciplines were married to systems engineering and engineering management topics and deliverables to create two versions of a course to improve the overall functionality of all Capstone design teams, as well as, their project's final outcome. To conclude, the benefits/disbenefits and success/lack of success of the two different formats is highlighted. © American Society for engineering Education, 2015.

This research presents the development and evaluation of a breath alcohol measurement device utilizing the MQ-3 alcohol sensor and an Arduino Nano-based control system. The primary objective was to design an accurate and reliable system for detecting breath alcohol concentration, with real-time feedback provided through an OLED display and an active buzzer for alerts. The device operates by measuring the alcohol concentration in the breath and converting the sensor data into parts per million (ppm). When the alcohol concentration exceeds the predefined threshold of 5% ABV, the system activates an audible alarm via the buzzer and displays the corresponding ppm value on the OLED screen. A series of tests were conducted with eight volunteers who consumed varying amounts of alcohol. The results demonstrated the system's high accuracy and responsiveness, with the ability to detect alcohol concentrations ranging from safe levels to dangerous thresholds. The device was tested multiple times to ensure consistency and minimize errors, with the final results confirming its effectiveness in providing reliable alcohol measurements. This system holds significant potential for applications in monitoring alcohol levels in drivers and individuals involved in safety-critical activities. The research underscores the importance of real-time alcohol detection systems in enhancing public safety and ensuring compliance with safety regulations.
